[Bug 386397] Re: ffmpeg gets "Illegal instruction" on Pentium II
this bug seems is valid to me it seems that mplayer is using a newer version of MMX than is supported on Pentium II machines. As easy workaround, you can move /usr/lib/i686/cmov/libswscale.so.0 out of the way. ** Changed in: ffmpeg-debian (Ubuntu) Importance: Undecided => Medium ** Changed in: ffmpeg-debian (Ubuntu) Status: Incomplete => Confirmed -- ffmpeg gets "Illegal instruction" on Pentium II https://bugs.launchpad.net/bugs/386397 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 386397] Re: ffmpeg gets "Illegal instruction" on Pentium II
I am experiencing the same problem. It seems to be related to the architecture and mjpeg handling. I could transform from h264 avi to flv without a problem, but when trying to extract a frame as jpeg I also got the "Illegal instruction" error: ffmpeg -i Fenix.flv -t 00:00:1 -f mjpeg Fenix.jpg FFmpeg version 0.5-svn17737+3:0.svn20090303-1ubuntu6, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --enable-gpl --enable-postproc --enable-swscale --enable-x11grab --extra-version=svn17737+3:0.svn20090303-1ubuntu6 --prefix=/usr --enable-avfilter --enable-avfilter-lavf --enable-libgsm --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis --enable-pthreads --disable-stripping --disable-vhook --enable-libdc1394 --disable-armv5te --disable-armv6 --disable-armv6t2 --disable-armvfp --disable-neon --disable-altivec --disable-vis --enable-shared --disable-static libavutil 49.15. 0 / 49.15. 0 libavcodec52.20. 0 / 52.20. 0 libavformat 52.31. 0 / 52.31. 0 libavdevice 52. 1. 0 / 52. 1. 0 libavfilter0. 4. 0 / 0. 4. 0 libswscale 0. 7. 1 / 0. 7. 1 libpostproc 51. 2. 0 / 51. 2. 0 built on Apr 10 2009 23:18:41, gcc: 4.3.3 Seems stream 0 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 50.42 (605/12) Input #0, flv, from 'Fenix.flv': Duration: 00:00:33.30, start: 0.00, bitrate: 1000 kb/s Stream #0.0: Video: flv, yuv420p, 640x480, 1000 kb/s, 50.42 tbr, 1k tbn, 1k tbc Output #0, mjpeg, to 'Fenix.jpg': Stream #0.0: Video: mjpeg, yuvj420p, 640x480, q=2-31, 200 kb/s, 90k tbn, 50.42 tbc Stream mapping: Stream #0.0 -> #0.0 Press [q] to stop encoding Illegal instruction Assuming Josh's backtrace is a proper one (never done one before) here is my output after press [q]...: [New Thread 0xb6e096c0 (LWP 4504)] Program received signal SIGILL, Illegal instruction.
